Research at Umeå University in Sweden shows that in the utricle – which is one of the internal ear's balance organs in mammals – epithelial cells can be regenerated, resulting in healthy sensory hair cells and surrounding ...

Cancer of the pancreas is an extremely aggressive disease with a dismal prognosis. The number of cases that is newly diagnosed with this type of cancer each year is almost the same as the one of people who succumb to it. ...

Benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate, affects about half the men between 51 and 60 years of age, and nine out of 10 men older than 80. How BPH happens, however, is still open for ...

Several scientific studies have indicated that nicotine may be beneficial for memory function. Scientists from the Institut Pasteur and the CNRS set out to shed further light on the properties attributed to nicotine - which ...

Researchers at UT Southwestern Medical Center have identified a previously unknown role of a cellular signaling molecule involved in release of the "hunger hormone" ghrelin, a finding that could have implications for optimal ...

Researchers at Technical University of Munich discovered that our brain actively takes sugar from the blood. Prior to this, researchers around the world had assumed that this was a purely passive process. An international ...

Many cancers only become a mortal danger if they form metastases elsewhere in the body. Such secondary tumours are formed when individual cells break away from the main tumour and travel through the bloodstream to distant ...

Researchers identified two types of olfactory receptors in human muscle cells of bronchi. If those receptors are activated by binding an odorant, bronchi dilate and contract – a potential approach for asthma therapy.

Reprogramming of the molecular pathways underlying normal metabolism is essential for T cell infection-fighting function and for the immune system to form a "memory" of the microbes it has already encountered. But exactly ...
